Abstract: PURPOSE:To obtain the composite roll of a two-layered structure having a high-strength inside layer by forming the outside layer of an alloy cast iron material and the inside layer of a material having a specific compsn. consisting of C, Si, Mn, Ni, Cr, Mo, Bi, REM, S, and Fe. CONSTITUTION:The cylindrical part of the roll is made of the two-layered structure consisting of the inside layer and the outside layer. The outside layer of this composite roll is formed of the alloy cast iron material. On the other hand, the inside layer is formed of the material contg. 1.4 to 2.5wt.% C, 1.5 to 3.5% Si, 0.3 to 1.O% Mn, <=1.5% Ni, <=0.8% Cr, <=0.5% Mo, 0.0006 to 0.005% Bi, 0.005 to 0.02% REM, and <=0.015% S and consisting of the balance Fe and unavoidable impurities. The structure which encloses the graphite in a 1 to 4% range of area rate as shown in Fig. and does not crystallize flake graphite is obtd. with the resulted inside layer. The strength of the inside layer is enhanced in this way and the crack of the roll at the time of rolling is prevented. The composite roll with which the increase of the cooling rate at the time of the low-temp. hardening and hardening of the outside layer is possible, is thus obtd.

Title: Electronic camera
Inventor: FUJII YASUTOSHI
IPC: H04N5/765
Filed: 1999-06-03
Abstract: PROBLEM TO BE SOLVED: To specify an image by means of a display, even if the correspondence relation between a frame number and an image before deletion is different from that after the deletion owing to image elimination by allowing a displaying means to display information including a frame number, corresponding to each image and a file name or a part of information of the file name as well as the image. SOLUTION: A user depresses a frame feeding button to make a displaying means show a frame number FR 2 (DISC0002 of file name FN) from among images stored in a storing means under the control of an MPU. The MPU deletes the frame number FR 2 from the storing means in accordance with the depression of an deletion button, based on user's desire and successively advances the next image to prevent a frame number FR from being a missing number. Consequently, the user can decide that three images are stored in the storing means by locking at frame numbers FR of the displaying means. In this way, since the relation of a file name FN and a frame number FR is different prior to the deletion and after the deletion it is possible to easily specify an image.

Abstract: PURPOSE:A process to reduce the equipment cost of a shipping line greatly without the fear of pressure increasing and the necessity to provide a high pressure tank on the way with the small capacity of a heater by mixing return gas into supercooled liquid. CONSTITUTION:Low temperature liquefied gas 2 in a low temperature liquefied gas tank 1 is sucked by a primary pump 3, and raised in the pressure by a secondary pump 3', keeping the phase of supercooled liquid. It is then resen in the temperature by a heater 4 and supplied to a shipping tank 8. Meanwhile, the return gas from the shipping tank 8, as the feedback to a shipping line, is returned to a drum 13 arranged between the primary and the secondary pump 3 and 3' to be cooled and liquefied, and can be easily pushed in because of its relative high pressure in comparision with the shipping gas. Since the supplied liquid is in a supercooled state, the return gas can be easily melted in and prevented from flowing backward into the low temperature liquefied gas tank 1.
